I'm such a geek.
I'm a big technology individual. I love science and technology, and anything that has to do with capturing events so that they can be experienced later.
In fact, I'm a geek.
I loved science. I still love it; I'm a nerd in that sense.
I call myself a nerd all the time.
I'm a total nerd.
I'm the biggest nerd you know. I'm a nerd, I'm a techie, and I don't have a problem with saying it.
I'm such a geek, and have always been a real nerd.
